How to connect an hood to the ventilation system correctly

Combination of natural ventilation and hoods in the kitchen in one channel

Most users are skeptical of the unification of hoods and ventilation in the kitchen in one channel. By this they deprive themselves of many advantages of their operation. If the ventilation channel serves one kitchen plate, the owner will not be able to connect to the natural system with the fueled unit disconnected.

Natural ventilation in the kitchen with hood is necessary to maintain a comfortable and healthy microclimate in the apartment. In addition, it allows you to protect users from harmful fumes allocated during cooking. The hoods alone in the kitchen are usually not enough, which forces users to deal with its compatibility with natural ventilation.

The principle of action of the latter is the directed movement of the air due to the pressure drop on the street and in the apartment. It is formed due to the difference in temperature, which is maintained in houses for most of the year. The main drawback of this system is the instability associated with the inconstancy of climatic conditions. As a result, the owners of the apartments have to check the presence of traction all the time. This is done in one of the proven ways.

How To Vent Range through Roof Instead of through Wall

In the first case, it is enough to take a sheet of paper and attach it to the kitchen ventilation hatch. If he immediately “sticks” to the hole, the system is working and the pressure difference is maintained at a normal level. Когда бумажный листок сползает вдоль стены, тяга отсутствует – вентиляция не работает или очень слаба.

The second method of verification is to bring a lit candle, match or gas lighter to the hatch of a light. With good rod, the flame deviates towards the ventilation hole.

If there are problems with a natural outflow of air, it will require cleaning ventilation shafts and existing air ducts, which forces to seek help from specialists. Under certain conditions, non.Working ventilation can lead to changing thrust. At the same time, the air from the street will begin to flow into the apartment, completely blocking the work of the hood.

Kitchen ventilation systems: natural or forced

Not everyone knows which ventilation scheme for the kitchen is better, the standard natural, when the exhaust gases go through the channel to the street or forced (a fan is used to remove contaminated oxygen). There is no unequivocal answer to this question, because each of the hoods performs its functions, has characteristic advantages and disadvantages.

In the kitchen, regardless of its location (in an apartment or private house), the presence of a natural ventilation system must. Particular importance must be given to the performance of the equipment, and especially if the room has a gas stove in the room. In this case, harmful emissions will be displayed on the exit on the vertical channel of natural ventilation. The hood rules do not consider forced ventilation to be compulsory engineering communication, it only provides the comfort of residents. Next, we describe each type of air exchange in more detail, consider their strengths and weaknesses.

Natural ventilation in the kitchen

Extra ventilation in the kitchen is familiar to all residents on vertical mines who have exit on the roof of a residential building. Harmful substances and evaporation are removed through such moves, and fresh air enters the rooms through the cracks in the windows or special valves on the frames. A warm, heated air stove, the air strives upward, it accumulates on the ceiling and goes through the ventilation hole outside the house. Fresh oxygen from the street comes to its place.

Correct, high.Quality mounted ventilation for the kitchen in the apartment allows a small amount of exhaust gas, but does it in constant mode. The ventricature cleaned of garbage is capable of removing carbon monoxide and minor fuel leaks from kitchen equipment. For high.Quality removal of extraneous odors, an extract above the stove should be mounted.

The supply ventilation has the following advantages:

  • High.Quality air exchange in the apartment;
  • The removal of harmful substances that are released during cooking;
  • Removal of smells and increased air humidity when several firewood is turned on;
  • Lack of financial investments on the operation of the system;
  • Noiselessness.

Ventilation in the kitchen with hoods has the following disadvantages:

  • Reducing the efficiency of work in the presence of hot weather;
  • The possibility of the reverse passage from the street to the kitchen;
  • A relatively small volume of processed air per unit of time;
  • You need to constantly check the traction in the ventilation room.

Not all suburban real estate owners know how to properly arrange a natural ventilation system in a private house. In this case, the channels will be made in the walls of outbuildings, such as the bathroom, toilet and kitchen. For high.Quality ventilation of the whole house, and not just these rooms, it is necessary to additionally let the air flow out of the bedroom, living room or dining room. In some cases, you need to keep the windows open.

If the kitchen has a four fireproof gas stove, then the hourly volume of the processed air should be within 90m3. For efficient operation of the ventilation system, it is necessary to install a channel with a section of 0.02m2. This parameter corresponds to the diameter of the pipe of 16 centimeters or a mine laid out of a square.Shaped brick with a side of the side of 14 centimeters. The entrance to the channel is located on the ceiling or at a distance of 20-30 centimeters from it. To ensure stable thrust, you need a ventilation duct of 5 meters long.

Forced exhaust system

By the concept of forced ventilation means an engineering system in which contaminated air flows are displayed using a fan. In the kitchen, such devices are mounted in different methods:

  • To a vertical ventilation shaft.
  • In the hole made in the wall of the building. In this case, the contaminated air will be excreted out of the kitchen, bypassing ventilation shafts.
  • The corrugated pipe from the kitchen hood can be inserted into the window.
  • Some consumers install a special device over the gas stove, hood. Polluted air can exit the kitchen into natural ventilation mines or immediately on the street through the hole in the wall.

The advantages of connecting an exhaust fan or kitchen hood are considered:

  • Improved performance. Effective ventilation in the kitchen allows you to quickly remove odors and harmful substances accumulated in the air.
  • The kitchen hood above the stove takes harmful substances before they get into the space of the room.
  • Dirty air is removed from the room only with a fan.
  • Such a system requires financial investments. In addition to the cost of the hood itself, you will have to constantly pay for the consumed electricity.

During the installation of the fan in the mine, you need to take into account several important points. The fact is that such a device has a check valve, which prevents the absorption of dirty air with a non.Working extract. This valve needs to be removed so that it does not interfere with the work of the natural air vent system. It should be noted that the productivity of the device will coincide with passport data only in the case of a horizontal outlet of the channel of a small length. The modern hood connected to the general house mine will have less performance compared to the declared technical characteristics.

What hood to install in the kitchen of a private house

Before you find out how to install an hood, it is necessary to determine what types there are devices and which filter system they are equipped. So that the cassettes not only eliminate the unpleasant odor, but also collect oily particles, a synthetic winterizer or non.Woven. Filters of this type are disposable. Reusable cassettes are made of aluminum or steel, special fatty fathers are used to clean them.

There are also coal filters that not only delay soot and fats, but also neutralize unpleasant odors. The disadvantage of such products is that they are disposable. According to the design features of the hoods, there are the following types:

Flat

Hoods of this type attract buyers in small sizes and simplicity of design. Since they do not have a chimney, they can be attached to the bottom of the mounted cabinet. If the size of the device is not enough to close the stove, you should pay attention to the extending models. Such products are suitable for rooms with a small area.

Flat hoods work on the principle of air recirculation. They absorb it with fans, clean, and then return to the room. As a rule, such products are equipped with coal filters.

Built.In

This type of hood also refers to the recirculation type. Since the device can be installed inside the hinged cabinet, it fits unreleased and harmoniously into the interior. The case has a cubic shape with a retractable panel for a larger air capture. First, the hood is installed in the wall, and then hang the cabinet.

Dome

The device of this type is characterized by a large voluminous form resembling a hemisphere or trapezoid. The design allows you to install powerful fans and several filters. Therefore, experts believe that the hoods of this species are the most effective. Cleaning can be recirculation or by connecting to a ventilation shaft. Such products are installed in rooms in which there is no access to fresh air.

Stages of installation

Installing the hood over the stove is that it must be fixed to the closet or support frame. This is done when installing a hinged or mortise model. Halled or built.In units are attached to dowels or self.Tapping screws. The island model will require a set of studs, fasteners, clamps.

Distinguish the stages of installation:

  • Fixation of a wall frame, installing hoods on it (hinged);
  • Installation of a prepared cabinet, installation of an unit in it;
  • Junction of the body with an air duct;
  • Connecting the hood to ventilation;
  • Organization of supply of electricity;
  • Launch and check of work.

Installation of island hoods is usually more complicated, since the equipment can be hung or built.In, for example, in the bar in the center of the room. Compact installations can be square, rectangular, in the form of a round or cylindrical dome.

Installation of hoods

For a hinged model, a metal profile is used from the corner on which the case with a fan and dome will be based on. First set support for marking, fixed to the wall. The hood is mounted on it, fastened with screws through the holes in the housing. Join the duct. Sometimes the hood is placed without a support frame, then the case is attached with dowels to the wall.

connect, hood, ventilation, system, correctly

The built.In model is attached to kitchen furniture. Self.Tapping screws, screws are used for fixation inside. To the vertical surface, the cabinet is hung with metal loops with holes under the hats of dowels. If the dimensions of the hood are small, you can connect the cabinet to the hood, then fix it together on the wall.

Island models differ more than the duration of the duct, t. To. Are located in the center of the kitchen. They are fixed depending on the structure on the supports, to the ceiling or in furniture items. Pipes are carried out on the ceiling, hidden behind drywall or plastic.

Installation of the air duct

Metal thin.Walled pipes are connected by bolts and flanges, attached to each other with bells, nuts, thick pipes are welded. Plastic products are joined by welding, in the bell, glued. The method depends on the material: polypropylene, polyethylene, polyvinyl chloride. Round channels are connected by couplings, bandages.

For fastening to the walls, options are used:

  • Threaded rods for fixing pipes with walls with a thickness of less than 1.5 mm;
  • Steel brackets, metal canals are fixed to them;
  • Clamps. They are installed on the walls with anchors, plastic dowels with self.Tapping screws;
  • Studs, traverses with a Z-shaped L-shaped profile.

There can be several types of fixation on one system to ensure the necessary strength, to reduce the possibility of vibration.

Connection of the hood to the duct

The corrugation is torn into the hole of the upper cover of the cabinet, cut with a margin, then the corners are cut, bend out.

  • A cabinet with a pipe is hung on a vertical surface;
  • The joints are smeared with silicone;
  • They are directly connected to the ventilator with a special grate with round input;
  • The corrugation to the hood is fixed with a clamp;
  • Along the path of the pipe to the hood, it is attached to the ceiling or wall with clamps.

The end of the corrugation is connected to the lattice, and the beginning is connected to the hood. The joints are glued with sealant before assembly.

Connection to electricity

Three conductions are used for connection: phase, zero and earth. Grounding is necessary to ensure the safety of the device in non.Standard situations when electricity pierces the case on the case. The grounding wire is standardly made yellow with a green strip, but it is better to check the voltage with a screwdriver with a screwdriver.

  • Sometimes, instead of grounding, they make a strain, conducting a cable (multi.Core, with a cross section of at least 2.5 mm) on a special tire in a camshaft;
  • On the batteries, the pipes cannot be connected, it is dangerous;
  • The sockets are placed so that it is easy to reach them;
  • The cord from the hood has a length of 0.8 m, based on this, the place of the outlet is determined. Sometimes use an automatic circuit breaker at 6.3a.

In the case of using a hinged hood, the outlet is installed behind a decorative casing, but so as to reach. In the built.In version, the connection point is provided inside the cabinet, while the hole of the corresponding diameter is provided in the back wall.

Operation, care

The instructions say: a fat.Down aluminum filter is changed every two months. We take a chance to assume that the instructions in the original language gives something like Renew, it is translated. Update. Rather, a fatty filter must be washed once every two months, avoiding buying a new. Otherwise, the device will become an expensive acquisition, for the year the service will eat money three times more than the cost of the unit. Check the issue of the manufacturer. You can get by on your own after buying. Just try to wash the fatter filter if the accessory accepts the previous condition, it will become like new, rather operate on.

The coal filter will have to change. Not so much alarms large size as the update period. 2 months. The manufacturer is not so cruel, indicates the term of six months, since the coal filter costs money. The instructions say: regenerate, washing components is unacceptable. Like the truth. The charcoal filter is located above the fat, used by the recirculation mode when the air just walks around. Not the best option for a gas stove, for an electric one. Nothing more is needed.

Annoying: the name is not indicated, the type of coal filter. A direct request from the search engine regarding the type of kitchen hood under consideration is powerless to give a positive result. The cunning dealers are strained, writing: the Hansa Fwu 60 coal filter is absent, you can order. The price is silent. We find it difficult to calculate the cost of the operation of the product, are deprived of the desire to call, by instilling certificates. Will have to take the steering wheel to the reader. We consider the installation of the kitchen hood in the review, not the problem of hard.Faced.

Components cost 250-800. Determined by manufacturers. Avoid bite to a gift, take a kitchen hood. Dear coal filters can serve six months, cheap. Two months. Simple calculation shows: we change the awl for soap. A year later, the cost of the product will be blocked. Dear kitchen hood, high.Quality, requires similar cost costs.

Installation of hoods for the kitchen is carried out according to the instructions. The manufacturers settings are specific, do not think that kitchen hoods are similar, like the brothers Gemini. It remains to say goodbye.

Classification

So, as mentioned above, the main separation of kitchen hoods is carried out according to the method of removal of contaminated air. The rest of the classification is based on the methods and places of installation, as well as the form of the device.

  • Suspended. They are attached to the wall above the stove or to the lower surface of the cabinet, which is also installed above the hob.
  • Built.In. Inserted into the kitchen set. They are not completely visible, except for the control panel.
  • Domed. Have a dome shape, which provides a more effective collection and removal of contaminated air masses.
  • Corner. From the name itself it becomes clear that the place of their installation is the angle of the room where the plate itself is installed.
  • Island. They are suspended to the ceiling above the kitchen island.

How to hang an extract above the stove

The method of installing and connecting the air pipeline from the kitchen stove to the venti.Channel depends on the type of household appliance:

connect, hood, ventilation, system, correctly

Build.Type exhaust devices are screwed to the finished box with self.Tapping screws or other mounts attached to the product. Before connecting the hood to ventilation, in the upper horizontal wall of the cabinet, make a hole with a diameter of 120-150 mm under the output of the pipe. If an additional shelf is provided above the box, then it will also have to be drilled.

The wall.Type device is attached in the following order:

  • Measure from the surface of the gas stove 75–80 cm and draw a horizontal fishing line for a trimmer on the wall with a pencil, using the construction level.
  • Sove the fastening points, focusing on holes or brackets on the hood.
  • Drill holes in the wall and forget plastic dowels.
  • Piece the exhaust umbrella using standard mounts.

The distance from the firepower of the electric stove to the lower plane of the hood is allowed to reduce to 60 cm. The reason is the absence of an open flame heating the surface and the internal details of the household appliance. Check if it is convenient to cook food at a low suspension height. If the case is visually suspended unevenly, the position of the hood can be adjusted using adjusting openings made in suspended brackets. Loosen one fastening screw, lift or lower the corresponding angle of the device and tighten the screw again.

Installation of island hoods consists in attaching the case to the floor on special brackets. The center of the slab is projected onto the ceiling, where the marking of the fasteners is applied. It is better to carry out work with an assistant supporting the device during installation.

How to hang an extract above the stove

If the hood is selected correctly, then it should be in width, either equal to the plate, or a little wider than it. In order to install an exhaust system, it should not only be placed, but also fixed. It should be located exactly above the surface of the plate.

Note! The parameters in terms of installation heights of the hood directly depend on the type of hob. If you have a gas stove, then the distance from the hob to the hood, in height, should be 75 cm; And if the plate is electric. At least 65 cm. Thus, in order to hang the hood over the gas stove and electric stove, you need to take into account various distances.

When deciding on how to establish an hood, you need to decide on the height before installation, based on the growth indicators of a housewife. If a woman rises straight, then the lower edge of the exhaust system should be slightly above her head. We do not recommend installing below this indicator. If you install above, it will not be critical.

Good to know! Answering the question of how to correctly install the hood over your gas stove, you must understand the following nuance: if there is a need to install a system higher than 90 cm. From the hob, then it is necessary to purchase an hood with increased power.

Let’s talk on the topic: “mount for modern hoods”. The fasteners of the exhaust system depends on its type:

  • The built.In kitchen hood should be attached to the surface of a specially designed cabinet for this.
  • The hinged system (flat) and dome (fireplace) hood is attached to the surface of the wall.
  • The island hood is attached to the surface of the ceiling: when buying, in the kit, a clear installation instructions are always given, and the entire suspension system.

Extensions are an integral element of a modern kitchen, which plays a very important role, removing extraneous smells from the room, which can form in the kitchen when cooking. This is due to the fact that cooking does not do without unforeseen situations, since many housewives practice the simultaneous performance of several works not only in the kitchen, but also in the house as a whole. As a result, the milk ran away, then the fish in a frying pan burnt, then the meat was overjoyed in the oven and the smell of burning appeared and t.D. If there are no hoods, then this “could” diverges throughout the apartment, especially since there is no need to talk about the quality of functioning of our doors. The hood installed above the stove easily copes with such problems. Of course, if everything is done correctly and competently.

The fact that the hood should have its own ventilation system is not even discussed, since this is the only way it can function effectively. To install air ducts from it in existing ventilation channels of high.Rise buildings is an unreasonable venture, although many go to this step. In multi.Storey buildings, reverse craving appears quite often, and this leads to the fact that extraneous smells fall into the kitchen from the street, including from working extracts of neighbors. You can deal with this only one way. By providing your extract a separate ventilation duct.

Recently, built.In hoods have been increasingly popular and this is not surprising, since they do not violate the overall style in which the kitchen is designed. The fact is that the built.In hoods are practically closed from the gaze of a person, like the air ducts along with all elements. Despite this, their functionality does not suffer from this. As a rule, the hood is installed by personnel who mounts kitchen furniture. Naturally, for a fee, although, both the cost of extracts and its installation can be included in the total amount of work, especially since many companies practice this approach. Of course, it is better to use the services of the masters, because it will be with whom to ask, and they will do it more professionally and more carefully.

If the furniture in the kitchen is old, but the hood must still be installed, then you can do it on your own, especially since the issues of culture of work performed cannot be in the first place, based on a similar situation. In such cases, an ordinary hood is suitable, which is attached directly to the wall. All elements of the duct can be left open, but it is better to use not aluminum corrugations, but components from PVC materials, since they have a more attractive appearance.
